Do not think that it was the Roller Cam profiles that were ever really an issue.
Some say the Roller Lifter durability was due to several things and the people selling that stuff to Pontiac Guys was rapidly dropping.
So you are correct. Personally if I put a roller cam in a Pontiac Engine the parts would come from ISKY period.
